摘要： A communication system comprises a plurality of line cards having transceivers coupled to a plurality of subscriber lines. Each line card has at least one active transceiver within the same vectoring group, and each line card also has vector logic capable of cancelling crosstalk induced by an active transceiver that is a member of the vectoring group. Further, the line cards are coupled to one another via a ring connection across which vectoring information is passed from one line card to the next. In the event of a failure of one of the line cards, the failed card is bypassed by the vectoring stream so that the operational line cards can continue crosstalk vectoring operations despite such failure.

摘要： An optical communication system comprises a network interface device (NID) having a media converter coupled to an optical fiber of a passive optical network (PON). The media converter converts optical signals from the PON into electrical signals for communication across at least one non-optical channel, such as a conductive or wireless connection, to customer premises equipment (CPE), such as a residential gateway or other customer premises (CP) device. Rather than implementing an optical media access control (optical MAC) layer in the NID, an optical MAC layer for handling PON protocols and management is implemented by the CPE, thereby effectively extending the customer end of the PON across at least one non-optical connection to the CPE. By implementing the optical MAC layer at the CPE, the complexity of the NID is reduced thereby lowering the cost of the NID. In one embodiment, in an effort to further reduce the complexity of the NID, the optical MAC layer is configured to control a laser-on state of an optical transmitter in the NID.

摘要： A system has a current mirror that has an input node and an output node and an avalanche photodiode (APD) coupled to the output node of the current mirror. The system also has a nonlinear voltage-to-current conversion element coupled to the input node of the current mirror that transmits current through the current mirror and the APD. Further, the system has a feedback path coupled between the output node of the current mirror and the voltage-to-current conversion element that senses a voltage across the APD and provides, based on the sensed voltage, an input signal to the voltage-to-current conversion element for controlling the element's output current, and the feedback path is arranged to limit a voltage of the input signal such that the output current is limited thereby preventing damage to the APD.

摘要： A communications system and associated method distributes media in a communications network. A Session Initiation Protocol (SIP) communication session call is established between a caller and a communications server. A message is transmitted from the communications server to the media server that includes Session Description Protocol (SDP) parameters for media provided by the media server. Media is delivered to the caller in a packet format in accordance with the Real Time Transport Protocol (RTP) to reuse the same socket as the source IP and port numbers and update RTP timestamps and sequence numbers. The media is transferred to the caller with minimal jitter buffer flushes and network resource usage.

摘要： Flexibility of handling of multicast information using an Internet Group Management Protocol (IGMP) is improved by overcoming failures to respond to group specific queries. Such failures occur when heterogenous host devices are used on a common network. When a failure to respond to a group specific query is experienced, a general query is used to obtain information that was not provided by the group specific query.

摘要： The present disclosure generally pertains to systems and methods for allocating bonding engines among bonding groups. In one exemplary embodiment, a provision module is configured to allocate bonding engines. When selecting a bonding engine for a new bonding group, the provision module only considers bonding engines residing on access modules that terminate at least one of the communication links of the bonding group. Out of the bonding engines residing on access modules terminating at least one communication link of the bonding group, the provision module selects a bonding engine servicing the least number of external links and assigns the selected bonding engine to the bonding group. The provision module also provisions the access modules terminating the communication links of the bonding group such that the selected bonding engine bonds such communication links during operation.
